By helping you keep your home at the temperature which you determine, and ensuring it stays that way longer, you spend less energy on heating and air conditioning, letting you save money on your every energy bill.

However, when considering your options, one of the most important things you need to think about is how long your choice of insulation takes to be fully installed in your home.

Spray foam does not start off as a dry substance when it is applied, and this means you will have to wait for the insulation to dry before it is completely safe to work around without any issues. If you are on a tight schedule, this may leave you worrying that you do not have the time to install foam insulation.

How long does it take for spray insulation to dry?

There are numerous factors you need to take into consideration when asking this question. You need to take into account variables like humidity and other weather conditions, such as moisture in the area being worked on, and even the temperature while the spray is setting.

As a general guideline, spray foam insulation dries in around 24 hours. This insulation can be applied directly to sheathing, but in most cases, you can have it applied to whatever building material you have used.

Some materials, however, may prove to be less receptive of the foam than others, and will thus require additional coats of the foam insulation in order to ensure it stays in place and does its job effectively. Extra coatings may also be needed depending on the weather at the time of application and the type of foam being used.

The fastest drying spray foam to install on your home is half-pound open celled spray insulation, because in most cases, it can be done with a single-pass installation- allowing you to get it done the first time around and not have to worry about it afterwards. Half-pound open cell foam carries all the benefits of foam insulation, and is much more economical than some other types of foam.

It is very important to note that open cell foam is strictly for indoor use only, as it does not hold up well against weather conditions. If you are looking to insulate the interior of your home for a very budget-friendly price, this is a great choice.

A stronger, more durable option

If you are looking for a much heavier duty foam insulation spray, there is another option available for you. This option is called two-pound closed cell foam which is a much denser version of the half-pound foam, being twice as effective per inch of thickness.

This foam is incredibly durable, and has much more structural integrity than the alternative, allowing it to be used for various exterior purposes too. It also has incredibly low vapour permeability, and is in fact classified as a vapour retarder.

It acts as a secondary bulk water and moisture barrier system, ensuring that your home is much less likely to succumb to things like mould and water damage than it would otherwise be.

No matter if it is open cell foam for the interior of your home, or heavy duty spray that can help to fortify your home against vapours, moisture, and other hazards- there will always be a solution that is right for you.

So if you’re building a new extension or just insulating your current property and you were worried how long does it take for spray insulation to dry, you have nothing to worry about.

Your new coat of insulation should take no more than around 24 hours to dry after the final coat is applied. These foam insulations can be applied to almost any building material you may have, making it the ultimate in convenience.

When you factor is its tight fit against your home, it becomes clear that there is no need to adjust your home in any way to accommodate this very easy method.
